Robley Rex, long known for his advocacy of veterans and as a volunteer at the Veterans Administration Hospital, has died.

He was four days short of reaching his 108th birthday.

Rex enlisted in the U.S. Army in 1919, a year after World War One. He served in the military for three years. After his military service, he dedicated himself to helping fellow veterans.

Wayne Pfeffer, the Director of the Louisville VA Medical Center, said on Tuesday, "Mr. Rex's capacity for serving his fellow citizens was truly an inspiration to all who knew him. He was a caring individual who consistently went out of his way to help others. His thoughtfulness, cheerfulness and sense of humor were treasures to those of us who had the privilege of knowing and/or working with him."
